how to calculate the arc length of a semicircle. An arc length R equal to the radius R corresponds to an angle of 1 radian So if the circumference of a circle is 2p R 2p times R the angle for a full circle will be 2p times one radian 2p And 360 degrees 2p radians A radian is the angle subtended by an arc of length equal to the radius of a circle. Enter the radius and total degrees of the rotation arc of the semi circle to calculate the area.
